How do I bind 2 java files so they both open when I run the jar file

Question

I think this can be done in eclipse? But how.

Basically what I want is to turn 2 java jars into 1 jar file and when I run it they both run.

Answer 1

There may be other ways, but one way to do this is by running the second jar file through the first file. You can run the second file as:

String cmd = "java -jar "+getClass().getResource("secondFile.jar").getPath().substring(1);
Runtime.getRuntime().exec(cmd);
